Actually had our Silk Road SDN (Nylon) carpet installed early 2019…. The layers did fine. The regret is that it keeps shedding ! Because it’s not woven but is glued, and assume this will continue forever! We told to snip these single bits of tufts to level of pile, and not pull them out! Be great if we reach a point where they stay glued! Have to vacuum in one direction which is time consuming and a frustration (a lesson learned). It’s also very drying on skin (bare feet) and would not choose this sort again. Not as brilliant as we’d hoped. A lovely feel, but combo or all wool if there is a next time for us!
